Zally validation for rule 151 does not accept reference code from rule 151

[Retro64]

https://opensource.zalando.com/restful-api-guidelines/#151 provides this example for the default:

responses:
  ...
  default:
    description: error occurred - see status code and problem object for more information.
    content:
      "application/problem+json":
        schema:
          $ref: 'https://opensource.zalando.com/restful-api-guidelines/models/problem-1.0.1.yaml#/Problem'

This leads to:

MAY – Specify Success and Error Responses

problem json has to be used as default response (https://zalando.github.io/problem/schema.yaml#/Problem)

Rule: https://zalando.github.io/restful-api-guidelines/#151

Location: paths > /pdfs > post > responses > default > content > application/problem+json

Substituting the ref resolves the problem:

responses:
  ...
        default:
          description: error occurred - see status code and problem object for more information.
          content:
            application/problem+json:
              schema:
                $ref: 'https://zalando.github.io/problem/schema.yaml#/Problem'

Either the reference from the guidelines should be accepted or the guideline should be adapted to show the "acceptable" URL.
